AUTOMATIC TRANSAXLE SYSTEM


  1. CONSTRUCTION


    1. An ATF warmer (transmission oil cooler) is used for the purpose of warming up the ATF quickly and to keep the ATF temperature higher (within limits). As a result, fuel economy has been improved.

    2. Engine coolant flows directly from the engine to the ATF warmer (transmission oil cooler) in order to warm up the ATF quickly even before the engine thermostat opens. As a result, the friction losses of the automatic transmission are quickly reduced, thus improving fuel economy.

    3. After the ATF warms up, the engine coolant that flows through the ATF warmer (transmission oil cooler) will help to limit the increase in ATF temperature.

    4. An air cooled oil cooler (oil cooler assembly) cools down the ATF using the cooling fins provided on the cooler itself, and is fitted inside the radiator grille so that it can be exposed to the air directly while the vehicle is being driven.*
